The FDA granted midostaurin accelerated approval in April 2017, and the EMA followed in September of the same year. These authorisations are for the treatment of adult patients with newly diagnosed acute myeloid leukemia (AML) who are FLT3 mutation-positive (as detected by an FDA-approved test) to be used in combination with standard cytarabine and daunorubicin induction and cytarabine consolidation. It was also approved for mastocytosis [3]. The EMA had previously granted midostaurin orphan drug designation for the treatment of AML and mastocytosis (effective via inhibition of KIT receptors on mast cells, which are involved in stimulating proliferation of mast cells in mastocytosis).Click here to link to ClinicalTrials.gov's list of Phase II midostaurin trials.
